 * 对Date的扩展，将 Date 转化为指定格式的String   
 * 月(M)、日(d)、12小时(h)、24小时(H)、分(m)、秒(s)、周(E)、季度(q) 可以用 1-2 个占位符   
 * 年(y)可以用 1-4 个占位符，毫秒(S)只能用 1 个占位符(是 1-3 位的数字)   
 * eg:   
 * (new Date()).pattern("yyyy-MM-dd hh:mm:ss.S") ==> 2006-07-02 08:09:04.423   
 * (new Date()).pattern("yyyy-MM-dd E HH:mm:ss") ==> 2009-03-10 二 20:09:04   
 * (new Date()).pattern("yyyy-MM-dd EE hh:mm:ss") ==> 2009-03-10 周二 08:09:04
